Isn't That 'Popping Sound' Bad For You?
No! Did your mother ever warn you that "cracking" your knuckles would give you arthritis? If she did, we're sorry to say that she was wrong! Research has actually shown that individuals who habitually "crack" their knuckles over their lifetime actually lower the incidence of arthritis in their knuckles compared with those who do not. The “cracking” or “popping” sound is simply the release of gas from within the joints. It’s a bit like when you open a fizzy drink - the “fizzing” sound is the release of pressure from the bottle - it’s the same with your body when the pressure is taken off the joints.
